Abstract:
    A solid product which comprises ammonium sulfate and ammonium nitrate and which contains a sulfamic acid compound is produced when an effluent gas having ammonia added thereto is irradiated with a radiation to thereby desulfurize and denitrate the effluent gas comprising SOx, NOx and CO, but the CO gas content being less than ten times the concentration of SOx. It is possible to remove the noxious sulfamic acid compound from the above-described product while preventing decomposition of the ammonium nitrate in the product which is useful as a fertilizer ingredient by heating the product at a temperature of from 130 DEG C to 250 DEG C, particularly from 180 DEG C to 250 DEG C.
